Analysis of the Structure and Abrasive Wear Resistance of White Cast Iron with Precipitates of Carbides

Abstract: The resistance of castings to abrasive wear depends on the cast iron abrasive hardness ratio. It has been anticipated that the white cast iron structure will be changed by changing the type of metal matrix and the type of carbides present in this matrix, which will greatly expand the application area of castings under the harsh operating conditions of abrasive wear. Detailed metallographic analysis was carried out to see the structure obtained in selected types of white cast iron, i.e. with additions of chromi… Show more

“…Therefore, property changes are achieved by adjusting the matrix microstructure to suit a specific application. Commercial ductile cast iron may present in its microstructure ferrite, perlite, ferrite-pearlite, cementite, martensite or ausferrite 5 . These phases can be obtained in the casting process by the chemical composition of the raw material, melting temperature, pouring temperature, inoculation, nodulization, cooling rate during solidification and by heat treatments 3,[5][6][7][8] .…”

“…Применение комплексного легирования вы-сокохромистых чугунов позволяет формиро-вать в них структуры, состоящие из заданного типа карбидов и соответствующей металличе-ской основы, что существенно повышает экс-плуатационные свойства литых деталей [16][17][18]20]. В период кристаллизации и охлаждения в этих чугунах образуются неравновесные струк-туры, вследствие чего при термической обра-ботке содержание хрома в карбидах повышает-ся, а в металлической основе -снижается [3, 5, 10, 11].…”

“…Therefore chromium cast iron is applied in industry of extractive, mineral processing, power engineering etc., mainly on components (castings) working at mining, crushing, grinding, transport etc. of minerals [1][2][3][4][5][6]. These castings during working are subject to destruction mainly due to the wear process, but sometimes it must also be resistant to momentary increase of load or impacts.…”
